MetacatUI

If a KNB view is taking a while to fully render, the loading icon displays at the top and the rest of the HTML and images are CSS-less, making it look odd. This can persist for several seconds, making a bad first impression. The loading page should be very simple, such as just the loading icon and a white background. OR the metacatUI CSS needs to be pulled from the server faster so that at least the full KNB header and footer are rendered while the loading continues.
